Lt. Raymond Evers says Temple University plainclothes officers began the pursuit at about 1:40 a.m. Sunday after a report of a man with a gun. Philadelphia police officers and a uniformed officer from a marked car also began chasing the suspect.

Evers says the man then turned and pointed a gun at the officer, who fired but missed.

A short distance away, the officer fired several more times and eventually hit the suspect in the right shoulder and neck. Evers says the 24-year-old suspect was taken to Hahnemann University hospital where he was listed in critical condition.
